What the developers have to say:

Why Early Access?

“We'd like Overdungeon to be easy to access, and involve and know community feedback as the game progress.
Additionally we have to adjust card and relic balances by community feedback and we'd like to know incredible methods that we weren't aware of.”

Approximately how long will this game be in Early Access?

“We aren't sure how long it will take but at least more than 1 year since we will add new characters and dungeons. We have to adjust game balance with whole parameters and we'd like to provide highest quality of new-style card game for community.”
